Tip: The clear hose will turn brittle from the antifreeze pretty fast. I used two 5cm pieces of chemical resistant clear hose in a boat where i installed a diesel heater system to help me see if there was air in the system, but the hoses became discolored and hard over the weekend. Had to change them out with proper radiator hoses, like the rest of the system. Also, you should add an expansion tank on the highest point of the system. It holds air that acts as a "damper" for when the system gets too hot. The liquid expands quite a lot when heated, and will burst your pipes. Air is compressible, liquid is not! But, i also have to say that this looks absolutely beautiful, and i am extremely impressed with what you have made!
Great point about the clear hoses, and the catch can is a must... The pressure valve in the cap probably didn't open with only a 20F temperature rise, but on a hot day it would for sure.
@@kschleic9053 He mentioned the operating pressure of the battery loop is only 2 psi. I'm guessing he's not going to run pressure valve at all and just a expansion tank.
@@Wooble57 @20:53 the radiator cap has the traditional pressure relief valve and a hose barb for overflow, so even if there is sufficient expansion capacity for 2psi, there should probably be an bottle on that hose barb just in case?
@@kschleic9053 opps, i forgot to reply to this, but as synthmilk said, he probably should. He should probably also put a thermostat of some sort on the battery loop, though if he doesn't put doors and such on he probably won't be driving in cold enough weather to worry about battery warming.
@@PlutonianPenguin I don’t know about sarcasm, but I think I heard some disappointment. He probably though it was cool, but just not his thing. Funny moment though
11:29 Just think.... He had to plan this transition and film the first part of it several weeks in advance and wait for the day when he could finally put it to use. THAT is dedication to detail!
This is an awesome series! I’ve watched every minute of it. I noticed you hard mounted the radiator. I would suggest isolating with rubber for vibration dampening. Aluminum radiators will crack if hard mounted. You plan on off-roading so I think it would be wise to isolate it!
@@ChickenSDS polyurethane is used a lot as a replacement for rubber in suspension bushings. So the same sort of stuff would definitely work to isolate the radiator.
@@Thats_Mr_Random_Person_to_you polly is harder than rubber, and woukd provide less protection for the radiator, although still better than hard mount i guess, but propper rubber rad mount grommets are easily accessible
I would recommend a thermostat for the battery coolant loop to bypass the radiator, and possibly a second radiator just for the batteries. On warm or hot days it doesn't matter, but on cold days you wouldn't want effectively freezing coolant pumping through the batteries. Regulating the pump speed can only do so much. You'll end up with unbalanced battery temperatures
yes but its not called a thermostat he needs a thermal probe in the coolant !! and some kind of logic to decide what to run and what to stop !!! maybe a dedicated arduino
@@fouzaialaa7962 his system can read temps, but he needs a way to restrict flow to the batteries without restricting the flow to the motor, since both run off a single pump
@Seema Kumari I think the fact that he makes fun of it means he probly laughed at your joke too. I went with the buzz cut because I get these big white patches in the middle of my brown hair, like a cow! What can I do but acknowledge that it is hilarious?!

1. Please add a reservoir to the cooling system. Leaks will eventually occur due to thermal expansion. That is the main reason they're used in cars. 2. As another commenter said, you have an aluminium radiator and copper heatsinks. Mixing these two metals is really not ideal as it leads to galvanic corrosion. It is advised to not do so in PC watercooling as well. Please look into this. I'm really pumped to see the Project Hummer EV finally on the road! Can't wait for all the fun stuff you have planned.
Also you will get losses of liquid out of the tubes themselves over time. It's one thing that can limit the lifespan of a lot of computer water coolers (All-in-ones at least) which often can't be easily refilled. It'd take years for it to be an issue, but it;s something to bear in mind with that much tubing.
I think the corrosion shouldn't be a problem because the water is deionized. So there isn't anything that can carry the electrons from one element to the other.
Great vid, looking forward to the next one! Just a quick note in case you see this. The plasticizers in the clear hose will likely leach out quite quickly into the propylene glycol solution and clog up any narrow pathways. You'll know this is happening when your hose becomes less flexible and will likely yellow. In water cooled PC's, this can happen within a few short weeks. I don't know of any clear flexible hoses that are free from this issue. Even in the PC cooling industry, the best of the best still have this problem, just delayed. We also use the same mix for PC cooling.
You're right, but plasticizers will only clog the extremely, extremely thin fins on a CPU or GPU block, a radiator (which is the narrowest pathway of a car cooling loop) won't be clogged
A few minutes after you were driving it around my Apple watch notified me that my heart rate had been over 120bpm while sitting still. So excited to see all the cool conversions of the future!
@@sayyidsahal1996 Yes, peak efficiency of 94% is possible, but that is for a specific interval of load and motor speed combinations. The average efficiency for a trip will be slightly lower, just like it is for combustion engines.

I have really enjoyed this series and it's awesome to see the E-Hummer out on the road. As for the cooling system, does it need to be more full (for lack of a better phrase)? It seemed odd to see air space in the lines.
Removing the air is called burping the system. You can only get so much of the air out initially. It needs to run for some time in order for the air to circulate back to the escape. Not a huge issue
@@lucaspohlmann7162 dont forget a PC will just sit there while the car will be driven. I would assume air bubbles will naturally pop while its in motion.
is it that necessary to show that on camera don't u conclude yourself that leaving the lid open while running it and talking about how the air is escaping is not enough for u to realize it is "full" after that?
Watching this series so long its like we share the excitement for the accomplishment Zack and the team did! Hearing that guy ask Gas or Diesel? With Zack answering "Electric" felt so wholesome 🤣
This seres has become my favourite series on youtube so far. Its so nice how you and us learn about electric vehicles and how relatively easy they are :D
My dad was a milkman in the 90s, I don't remember his electric milkfloat being quite so complicated. But saying that, I don't remember it going much faster than 25mph, and that was usually going down hill. I loved riding around on those old milkfloats. There was something peaceful about gliding through the morning, being able to hear the birds and enjoy the stillness.
I've literally saved this video all day to watch once my daughter went to bed. I didn't think she would ever go to sleep. But totally worth it. Love all your videos, but this series has me hooked.
Wow !! From rags to richies!! That was awesome to see you take it to the streets for the 1st time. It was fun watching you built this thing from scratch.
On the heating of the battery, you actually want to hold it at 26° it's actually really good for it. You'll actually notice the difference when you do. There's less voltage sag, so you'll notice it almost immediately once you start to push it.
Definitely noticeable on a Tesla, that is for sure. When everything is at the right temperature, the car feels far zippier at the same state of charge.
I absolutely love following this series. Been here since the beginning and it's insane how far you've come with this build. Can't wait to see what the future brings for it!
Zack again, incredible series! The best on UA-cam by far. As you said it sounds and handles like a bucket of bolts, my question is how difficult would it be to add air suspension like your Rivian? These old military shocks seem to be well past their time. But it is incredible to see it moving. Well done
I feel like Zach will eventually do some suspension work. Just seems too bumpy for a city street. At 27:28 forward Zach was getting a little bit of a rodeo treatment. BTW, this is the coolest conversion I've ever seen. Thanks Zack!
I Agree With Kevin Hosea, THIS Is The BEST Series Content. I’ve Seen Over The Entire Series Of Yours, Going BACK To The Very Beginning, Jerry. And NOW that I have Watched almost every episode of this process. I’m wishing I had the Access to the equipment and the people who helped you make this Ev HumVee. Because My Father had a Small Hand in the Development Of This Vehicle, The HumVee. While he was assigned to the United States Army’s Transportation School At Fort Eustis, Va, near Williamsburg,Virginia. I’m so wishing I could get to build my own Ev HumVee like you have, Sir. Doesn’t look like I will. So thanks 🙏 so very much for sharing this with with Us.
Hello Jerry from India. I have been a fan of your videos since a very long time I’d say since 2018 and this Humvy rebuild as Electric has been your coolest project thus far. You are very informative and detail out everything. It shows the kind of passion you have for the things you do. Keep up the good work your faithful subscriber.
I’m obsessed with this series and project. I have a 1999 Tahoe that I want to eventually convert to an EV. Super well done. Informational and educational and entertaining. Plus I live in the PG area and I cannot wait to see the Hummer in the wild. Huge fan - way to go!
I am from AF and loved seeing all of the places I went to back in the day. I also wonder if I will see this out and about, though I may geek out if I do.
This is really getting sweet now. Are you planning to clean up the truck after the build is done? i.e. de-rust old parts, tighten the frame up so it's less rattly, new paint job, etc. I think this build really deserves the full makeover. :P
Super cool to see it driving around town at last, but what's even more cool is this repurposing of older vehicles. Giving older vehicles another chance at life with newer technology. Can't wait to see this off-road where the torque will really come into its own👍
@@chafarlefeu I mean, any physics formula with temperature should be handled in Kelvin. Celsius Degrees should be good only when dealing with ΔT because Kelvin and Celsius Degrees share the same intervals between units Edit: spell check
@@KekkusMaximus yeah I know but the point of my answer was to warn the general public of this video which is for the most part not aware that this formula is useless if not used properly
If you charge immediately after driving in cold conditions the batteries will be in the range for charging its only if leave battery empty in cold conditions that will have problems
@@jwalster9412 Due to the high efficiency of the motor it is good at turning but not producing heat, so it would waste a lot of energy compared to a resistor in this case.
I do enjoy this series, not gonna lie I really do. I can't even hold how happy my face is when FINALLY this project come to its finish, and watching how it will be done in couple next videos is my top list now. I'm from Indonesia btw
@@JerryRigEverything NO RESERVOIR? What about thermal expansion??? You could get leaks in the system without a reservoir that's one of the big reasons they're used in cars Also your radiator seems to be aluminium, but the heatsinks in your battery might be copper... which will lead to galvanic corrosion, and eventually your system will leak (hopefully not inside the battery or it will destroy it). Just make sure you're not mixing metals!!
@@Extrinityishere Going out on a limb and saying a lot more than 50k (including the hummer) but less than 75k. Batteries can be had on open market 950-1350 per module, believe he has 16? so around 15-18500 (largest cost of this conversion). The motor and remainder components easily sit at 20-25k then rest of the cost of the vehicle itself. There could be labor if your not doing this or isn't simply a bolt on, which most conversions aren't. Again depending on how you approach this could easily get you under or at 75k for this project..
I didn’t realize there was such an efficiency difference between electric and gas engines. So, even if the electricity generated for the electric motor is created by fossil fuels, it seems like it would still be more efficient than a gas motor.
It absolutely is. Engineering Explained has some good videos about this... A gas turbine peaker plant, connected to an EV by miles of transmission lines and all the efficiency losses involved, AND the charging losses, AND the drivetrain efficiency, is still more efficient than gasoline explosions pushing pistons 😂
@@sayyidsahal1996 that depends, a natural gas turbine plant is about 42-45% efficient. A combined cycle natural gas plant (one that uses waste heat from the gas turbine to turn a steam turbine) can be upwards of 60% efficient.
Wow! I really dig how quiet it is. After driving Hummers in the Army and how loud they are (those that have driven military HMMV’s know exactly what I’m saying) you have to yell to your passenger next to you and if you have troops in the back seat you can forget talking to them at highway speed. Of course we used headsets most of the time to communicate. But yeah they growl, groan, rattle and moan ridiculously, this thing sounds great comparatively. Nice work!
Congrats on a job VERY well done! I didn't see how you flow the coolant through the battery packs... hopefully in parallel, not series? That way you can keep them all at the same temperature instead of sending "once warmed" liquid from the first - to the second battery pack, then "twice warmed" from the second to the third... It also looks like the suspension could be softened a little since it's probably a few (or several!) hundred pounds lighter than the suspension was designed for.
When you finish the Hummer you should also test it against another Hummer in offroad, track lap race and drag race, so we can see the differences in performance!!!!!
“If you have ever put your head out of the window on the freeway to let the wind blow through your hair like I do, you know what forces we’re fighting against” 13:40
This is the first time I am thankful for an advert. Just finished Project Hail Mary on Audible, what a book! Loved it!. Thank you for recommending. Waiting for your next video
30~40% conversion efficiency is a best case scenario for gas cars, such as with Hybrids. Typical gas cars are only ~20% efficient. Compare that with the >95% efficiency of EVs, and it's no contest.
you're forgetting that the electricity has to come from somewhere coal fired power stations for example are at best 40% efficient and are with that one of the most efficient power sources of the world
Nicely explained. However, I'd like to give my two cents as well. On one side, an expansion tank would be, as some others have said, quite necessary, not only because water expands and contracts but also because althought the system may have no leaks in theory, in practice there may be some if, for example, the lid of the radiator allows some vapor to be released when it reaches a certain pressure. All in all, the temperatures this system should work are nowhere near what an internal combustion engine has to deal on a regular basis, but that adds that extra peace of mind. And secondly, from what I see, there are some higher and lower spots, for example the top of the, I think it's the part in front of the engine, right where those clear hoses meet some angle pipes. There's some air trapped in there as, again, it's a high spot, and that air is going nowhere and therefore decreasing the efficiency of the system. It may not be something to worry, as it actually works in lower temperatures than, again, internal combustion engines, but it will certainly make the system work harder and therefore more power consumption. So, I think some kind of purging valve should be placed there and anywhere else where there's a local high spot in the circuit. If you're changing your piping for another one that can actually deal with antifreeze (as someone else has suggested) I wouldn't hesitate. Thanks!

I've literally saved this video all day to watch once my daughter went to bed. I didn't think she would ever go to sleep. But totally worth it. Love all your videos, but this series has me hooked.
Wow !! From rags to richies!! That was awesome to see you take it to the streets for the 1st time. It was fun watching you built this thing from scratch.
On the heating of the battery, you actually want to hold it at 26° it's actually really good for it. You'll actually notice the difference when you do. There's less voltage sag, so you'll notice it almost immediately once you start to push it.
Definitely noticeable on a Tesla, that is for sure. When everything is at the right temperature, the car feels far zippier at the same state of charge.
I don’t want this series to end but it’s going to have to! Been loving the updates
Everything just coming together makes me happy
Seeing the excitement in your face on the road is so satisfying. Glad she’s up and running….and legal!! Keep up the great work!
I absolutely love following this series. Been here since the beginning and it's insane how far you've come with this build. Can't wait to see what the future brings for it!
I love seeing the way you dissect problems and find solutions. Great series!
Zack again, incredible series! The best on UA-cam by far. As you said it sounds and handles like a bucket of bolts, my question is how difficult would it be to add air suspension like your Rivian? These old military shocks seem to be well past their time. But it is incredible to see it moving. Well done
I feel like Zach will eventually do some suspension work. Just seems too bumpy for a city street. At 27:28 forward Zach was getting a little bit of a rodeo treatment. BTW, this is the coolest conversion I've ever seen. Thanks Zack!
Air suspension would be so cool and comfortable, i hope he does it
By far the dopest video ever! I really want to see a drag race between the old and new hummer ev!
I Agree With Kevin Hosea, THIS Is The BEST Series Content.
I’ve Seen Over The Entire Series Of Yours, Going BACK To The Very Beginning, Jerry.
And NOW that I have Watched almost every episode of this process.
I’m wishing I had the Access to the equipment and the people who helped you make this Ev HumVee.
Because My Father had a Small Hand in the Development Of This Vehicle, The HumVee.
While he was assigned to the United States Army’s Transportation School At Fort Eustis, Va, near Williamsburg,Virginia.
I’m so wishing I could get to build my own Ev HumVee like you have, Sir. Doesn’t look like I will.
So thanks 🙏 so very much for sharing this with with Us.
This project is so awesome. Very happy for you Zack
are you planning to do some "finishing touches" to the EV (like non critical upgrades such as a good seat, reducing rattling, paint-job? comfort?)
Hello Jerry from India.
I have been a fan of your videos since a very long time I’d say since 2018 and this Humvy rebuild as Electric has been your coolest project thus far. You are very informative and detail out everything. It shows the kind of passion you have for the things you do.
Keep up the good work your faithful subscriber.
By far the best series on UA-cam..mad respect Zack love the videos
I’m obsessed with this series and project. I have a 1999 Tahoe that I want to eventually convert to an EV. Super well done. Informational and educational and entertaining. Plus I live in the PG area and I cannot wait to see the Hummer in the wild. Huge fan - way to go!
I am from AF and loved seeing all of the places I went to back in the day. I also wonder if I will see this out and about, though I may geek out if I do.
This has been an outstanding journey. Pure awesome!
"We are sticking the nipple inside a drill and rotating it against a bandsaw"
Sounds like a wild night
What are you doing, step drill bit?
This is really getting sweet now. Are you planning to clean up the truck after the build is done? i.e. de-rust old parts, tighten the frame up so it's less rattly, new paint job, etc. I think this build really deserves the full makeover. :P
Fantastic journey from day one of the Humvee project.
This looks like a gaming PC cooling system so now it just needs some sweet RGB
Yes we need rgb and some gaming chairs
Yeah! Thought the same thing
Never disappointed to see a new video of yours!
Super cool to see it driving around town at last, but what's even more cool is this repurposing of older vehicles. Giving older vehicles another chance at life with newer technology. Can't wait to see this off-road where the torque will really come into its own👍
I'm so proud to see the Humvee going around, like I've built it myself lol Amazing project..
This project is so amazing, I wish there were more youtubers doing high quality content like this!
Being a Utahn, I'd love seeing this thing driving around in person! Coming together very nicely!
13:45 “if you ever get it your head out the window to let the wind run through your hair like I do” 😂 made my day!
10:00 This kind of pressure change can also be observed doing natural gas pipe testing. The formula (for air anyway) is T1/T2 = P1/P2.
IN KELVIN for people reading this, in KELVIN, not fahrenheit, not even Celsius !!!! Exclusively in Kelvin or the formula makes absolutely no sense !!!
@@chafarlefeu I mean, any physics formula with temperature should be handled in Kelvin. Celsius Degrees should be good only when dealing with ΔT because Kelvin and Celsius Degrees share the same intervals between units
Edit: spell check
@@KekkusMaximus yeah I know but the point of my answer was to warn the general public of this video which is for the most part not aware that this formula is useless if not used properly
Great work Jerry, she is another big step closer to finished
Watching this project going from start is like watching a child growing up man I feel old
It would be interesting to have a heating system for the batteries to recharge them in temperatures below freezing.
Bypass valve to redirect motor heat through batteries not rad? :)
@@XxTWMLxX It's a good idea, but it might not work very well because the car is stopped to recharge, so the motor won't produce heat
If you charge immediately after driving in cold conditions the batteries will be in the range for charging its only if leave battery empty in cold conditions that will have problems
@@lucasdiniz5642 just put the motor at 5Krpm or something with the transfer case off.
@@jwalster9412 Due to the high efficiency of the motor it is good at turning but not producing heat, so it would waste a lot of energy compared to a resistor in this case.
I do enjoy this series, not gonna lie I really do. I can't even hold how happy my face is when FINALLY this project come to its finish, and watching how it will be done in couple next videos is my top list now. I'm from Indonesia btw
awesome video! love this project. are you going to provide a cost range of how much it cost to do this conversion?
Yup!
@@JerryRigEverything My Guess is between $50k-150k
@@JerryRigEverything NO RESERVOIR? What about thermal expansion??? You could get leaks in the system without a reservoir that's one of the big reasons they're used in cars
Also your radiator seems to be aluminium, but the heatsinks in your battery might be copper... which will lead to galvanic corrosion, and eventually your system will leak (hopefully not inside the battery or it will destroy it). Just make sure you're not mixing metals!!
@@iamdmc unrated
@@Extrinityishere Going out on a limb and saying a lot more than 50k (including the hummer) but less than 75k. Batteries can be had on open market 950-1350 per module, believe he has 16? so around 15-18500 (largest cost of this conversion). The motor and remainder components easily sit at 20-25k then rest of the cost of the vehicle itself. There could be labor if your not doing this or isn't simply a bolt on, which most conversions aren't. Again depending on how you approach this could easily get you under or at 75k for this project..
I didn’t realize there was such an efficiency difference between electric and gas engines. So, even if the electricity generated for the electric motor is created by fossil fuels, it seems like it would still be more efficient than a gas motor.
It absolutely is. Engineering Explained has some good videos about this... A gas turbine peaker plant, connected to an EV by miles of transmission lines and all the efficiency losses involved, AND the charging losses, AND the drivetrain efficiency, is still more efficient than gasoline explosions pushing pistons 😂
@@kschleic9053 Also, not all electricity is produced by fossil fuels, while to run a gas motor, it's entirely fossil fuels
how much efficient is a gas power plant?
@@sayyidsahal1996 About 40 - 50%, the upper end being for combined cycle gas turbines (CCGT)
@@sayyidsahal1996 that depends, a natural gas turbine plant is about 42-45% efficient. A combined cycle natural gas plant (one that uses waste heat from the gas turbine to turn a steam turbine) can be upwards of 60% efficient.
Wow! I really dig how quiet it is. After driving Hummers in the Army and how loud they are (those that have driven military HMMV’s know exactly what I’m saying) you have to yell to your passenger next to you and if you have troops in the back seat you can forget talking to them at highway speed. Of course we used headsets most of the time to communicate. But yeah they growl, groan, rattle and moan ridiculously, this thing sounds great comparatively. Nice work!
"GAS OR DIESEL?"
"ELECTRIC 😎"
This is super exciting! Nicely done ✅

So cool 🤙🏼
Thanks for making this & taking us along the journey!
Congrats on a job VERY well done! I didn't see how you flow the coolant through the battery packs... hopefully in parallel, not series? That way you can keep them all at the same temperature instead of sending "once warmed" liquid from the first - to the second battery pack, then "twice warmed" from the second to the third... It also looks like the suspension could be softened a little since it's probably a few (or several!) hundred pounds lighter than the suspension was designed for.
This is like a great TV show…. Waiting for the next one is the worst part!! Loving the series!
The Satisfaction he Must Have Felt, All the Hardwork Working when he was driving it on the Street, Love This Project 😍😍 And Love You MAN!N!!!!🥰🤩😘
When you finish the Hummer you should also test it against another Hummer in offroad, track lap race and drag race, so we can see the differences in performance!!!!!
Awesome! What is the before and after weight of the project? I wonder if you will need to make some adjustments to the suspension?
I'll weight it in my next video. And for sure, the suspension is super stiff.
When he was out driving I had the biggest smile on my face! Honestly most ambitious project I've seen actually come together. Amazing!
I love this project ❣️

This is the first time I am thankful for an advert. Just finished Project Hail Mary on Audible, what a book! Loved it!. Thank you for recommending. Waiting for your next video
You gotta give it a good suspension. Definately needs it.
30~40% conversion efficiency is a best case scenario for gas cars, such as with Hybrids. Typical gas cars are only ~20% efficient. Compare that with the >95% efficiency of EVs, and it's no contest.
you're forgetting that the electricity has to come from somewhere
coal fired power stations for example are at best 40% efficient and are with that one of the most efficient power sources of the world
@@simeoneon1980 but if its solar or wind
@@ΡΑΦΑΗΛΠΛΥΤΑΣ Solar and wind is 10% of the global electricity. Yeah.
@@UhOhUmm nucleair man
@@simeoneon1980 nucleair
One of the coolest series on UA-cam.
Nicely explained. However, I'd like to give my two cents as well. On one side, an expansion tank would be, as some others have said, quite necessary, not only because water expands and contracts but also because althought the system may have no leaks in theory, in practice there may be some if, for example, the lid of the radiator allows some vapor to be released when it reaches a certain pressure. All in all, the temperatures this system should work are nowhere near what an internal combustion engine has to deal on a regular basis, but that adds that extra peace of mind.
And secondly, from what I see, there are some higher and lower spots, for example the top of the, I think it's the part in front of the engine, right where those clear hoses meet some angle pipes. There's some air trapped in there as, again, it's a high spot, and that air is going nowhere and therefore decreasing the efficiency of the system. It may not be something to worry, as it actually works in lower temperatures than, again, internal combustion engines, but it will certainly make the system work harder and therefore more power consumption. So, I think some kind of purging valve should be placed there and anywhere else where there's a local high spot in the circuit. If you're changing your piping for another one that can actually deal with antifreeze (as someone else has suggested) I wouldn't hesitate.
Thanks!
